This invention relates to machines for punching holes in cards andstenclls, and 1s partlcularly adapted for making code punch.-

mgs in cards and stencils used in controlling selector mechanisms, suchas addressing machines, tabulatingmachines, weaving ma chines,and thelike.-

The main objects of' this invention are to provide an improved form andarrangement of punches; to provide improved mechanism for selectivelyoperating said punches; to provide improved means foraccuratelyguiding aseries of cards past a fixed point along a definite path and formomentarily holding a card at said point while it is being operatedupon; to provide improved operating mechanism tor intermittentlyactuating said holding means; to provide operating mechanism of thiskind controlled by the movement of the punching mechanism so 'as toinpositioning of the card at the critical moment; and to provideimproved mechanisms and'means of thiskind whereby two adjacent cards maybe operated on simultaneously. I

Fig. 11 is an enlarged detail of the card positioning mechanism:

Heretofore, stencils and cards used in controlling selector mechanismsusually have been punched by hand, while being held in a suitable masterplate or templet. The machines, sometimes used for making punchings,heretofore have consisted of a single punch which in some cases waslaterally shiftable across the'templet, while, in other cases, thetemplet or master plate and the card to be punched were'laterallyshiftable relative to the punch. Such prior forms of punches have beenvery and otherwise generally unsatisfactory.

In the specific construction herein shown, the present invention isapplied, to a punching machine having improved mechanism for selectivelyoperating a battery of punches so that a series of cards or stencils maybe fed through the machine in continuous, rapid succession.- The cardsare fed from a magazine or hopper (not shown) along a guideway in astep-by-step movement to the'punching position Where they' nism which iscontrolled by the operation of the'punches so that, upon each downstroke of the punches-the holding means is actuated to effectively holdthe card or cards operated upon.

In the specific construction herein shown, machines comprises a frame 1,having a horizontal guideway 2, along which a series of cards orstencils 3 upon by one or more of a battery of punches 4 which arearranged for selective operation through the movement of a verticallyreciprocating head 5, which is mounted in the frame 1. Arranged adjacentthe guideway 2, is improved holding and positioning means 6 adapted tomomentarily hold two adjacent cards 3 punching operation. The holdingmeans 6 the vcode in rapid succession 1 'statlonary during the ill bythis machine,

'retaining them on the is intermittently actuated by improved mechanism7 controlled in its operation by the movement of the head 5.

As herein illustrated, the frame 1 comprises'a base plate 8 and a topplate 9 connected together by upright posts 10 which slidably supportthe head 5.

The guileway 2 is formed in a pair of spaced guide blocks 11 and 11.1which are rigidly mounted on the base 8 and secured thereto by bolts 12or other suitable fastening means.

One form of stencil adaptedto be punchel and which is in common use inaddressing machines, is shown in Figure 3. This stencil con'i'prises'athin membrane 13 mounted in a cardboard frame 14 having a recess 15 inone edge thereof which forms a sight opening through which the indexcards may be visualized when the cards and stencils are stackedvertically, as is well understood. Formed in the frame 14, are apertures16, or code punchings, the

positions of which determine the selection, as is also well understoodin the art, and which may be arranged so close together as tooverlap-one another to provide for a large number of classifications orselec- The punches 4 are arranged in two rows,

extend-through openings 17 1n the guide: blocks 11 and 11.1. Formed inthe base plate 8, in register with the openings 17, are apertures 18to'rec-eive the lower ends of the punches 4. The upper ends of thepunches 4. are provided with heads 19 for head. The space betweenadjacent punches 1s equal-to the distance between alternate apertures 16in the card or stencil ,to be operated upon, and fbr this reason thepunches are arranged in two groups, as shown in Fig. 10,,so" as to beadapted to operate on two stencils simultaneously, ()ne group of thepunches 4 is located adjacent one end of the guideway 2 for punchingalternate apertures 16 in the cards 3, while the other group of punchesis located adjacent the other end of the guideway for punching the otherset of alternate apertures. For instance, apertures locatedin'positions1, 3, 5, 7 ,9, etc. on the card arepunched while the card is held at oneend of the guideway 2, while the intermediate apertures located inpositions 2, 4, 6,8, 10, etc. are punched while the card is held at theopposite end of the "uidewa With this nn roved arran ement b D ofpunches it is-possible to punch apertures which overlap one'anotherwhich would not be possible with a single set of punches withoutproviding for a relative adjustment between the card and punches.

In the specific construction herein shown,

the head 5 is in the form of a reciprocatarm 24, which is oscillated bythey reach I,

'ing carriage comprising a horizontal plate 20 having bosses or'bcaringparts 21 which slidably engage the upright posts 10 of the frame 1.Projecting upwardly from the plate 20, is a pair of lugs 22 connected bylinks 23 to the ends of a fork-shaped rocker any suitable means, notshown, for continuously reciproeating the head 5. v

- Suspended from the plate '20, by bolts 25 or other suitable fasteningmeans, is a supporting plate 26, having two rows of apertures 27 formingseats or loosely supporting the punches 4 is spaced from the plate 20 bysuitable washers 28 so as to permit the punches 4 to move axiallyrelative to the head. relative. movement of the punches and head,permits those punches whichare not in the particular selection, to restonv top of the stencil frame 14, while the head 5 continues its downwardmovement and while the selected punches are bcing'forced downwardlythrough the stencil frame 14. To selectively operate the punches 4, theyare snostantially locked against axial movement, relative to the head 5,by means of keys or wedges 2!) which are individually insertable betweenthe heads 19 of the punches 4 and opposed parts of the are seated inhorizontal seats or opemngs 30 formed in a pair mounted on the lowerface of the plate 20. To secure the 'keys 29 against accidentaldir-aplacement from the seats 30, they are head 5. The keys 29 of spacedblocks 31 The supporting plate 26 This ill)

are adapted to engage the heads 19 of the punches 4 to hold the selectedpunches in their downwardly extended positions relative td the head 5.If desired, the keys 29 may be operated by a key board controlmechanism, not shown, which will enable the operator tochange the keysand corresponding punches more rapidly.

The cards and stencils are fed along the guideway 2 in a step-by-stepmovement, by any suitable means, not shown, and when the punchingposition, the two adjacent cards located directly beneath the punchesengage a pair of steps 38 against which they are urged by the improvedpositioning means 6.

The stops shown in our copending application,- Serial No. 746,808, filedOctober 30, 1924. These steps are in the formof bell crank levers lo- 38are substantially like those into the path of the 39 of the rear guideblock secured to the block by pins of each of the levers 38is, shoulder42 which projects stencils for successively halting them as they reachthe critical'point where they are to be acted upon by the punches. Theshoulders 42 are yieldingly held in operative'position by tensionsprings 43 which are connected to pins 44 mounted on the block 111 andthe outer arms 45 of the outed in recesses 11 and pirotally it). One arm41 provided with a bell crank levers 38. lVhen the cards are.

forced forward from one position to the next, the levers 38 are forcedback against the action of the springs'43 so that the tips of theshoulders 42 ride on the edges of the cards until they drop into thenext corners In the specific construction herein shown, the improvedpositioning means 6 includes a pair of fingers 46, the ends of which areshiftable in recesses 47 formed in the guideblock 11.1, for engagementwiththe stencils 3 to urge the stencils transversely into lirmengagement with the guidcblocks 11 and t'orwardly into engagement withthe shoulders 42 of the stops 38.- The recesses 47 are spaced apartsubstantially the length of a stencil. in order to preventpossibleinjury to the cards by, a positive action of the fingers 46, thesefingers are pivotally secured to one end of a pair of levers 48 by pins49. The levers 48 are pivotally secured to the base plate 8 by pins 50.Bearing between the other ends of the levers 48, and the guideblock11.1, are compression springs 51 which normally urge the pivot pins 49of the fingers 46 toward the guideway. In order to-operate both of thefingers 46 simultaneously, they are connected by a link couplingincluding arms 52 and 53 pivotally connected to the pins 49 ot' thelingers 4b. and connected together by a link 54. The arms 52 and 53 are'spacedabove the fingers 46 by suitable washers 55 embracing the pins49. Embracing the washers 55, are springs 56 which bear against studs57, 58 and 59 respectively mounted on the fingers 46 and arms 52 and 53.The springs 56 form a; yielding connection between the fingers 46 andarms 52 and 53.

In the. specific form shown, the operating mechanism 7 forintermittently actuating the'positioning means 6, includes a verticallydisposed rock shaft 60 journaled in the frame 1, and a verticallyreciprocating cam 61 pivotally mounted on a bracket 62 which pro-v jectsupwardly from the head 5. Fixed on the lower end of the rock shaft (50,is an arm (33 which is connected to the arm 53 by a link 64, so that therocking of the shaft GO causes a rocking of the arms 52 and 53 aroundthe pivots 49, and a rocking of the fingers 46 through the springconnections 56. The rock shaft 60 an'd fingers 46 and the intermediatelink coupling are normallyurged to actuate the fingers 46.

into the retracted position, shown in Figure 10, by a sprihg 65 which isconnected at one end to a stud 66 mounted on the base plate 8 and at itsother end to a pivot pin 6'? which connects the link 54 to the arm 53.lliounted on the shaft 60, is a pin 68 carrying aroller 69 arranged toengage the cam 61 upon each down stroke of the head 5, for rocking theshaft'60 against the action of the spring 65 7 5 In the constructionherein shown, the cam 61 is pivotally secured-at itsupper end to thebracket 62 by a .pin Z0. The lower'end of the cam (51 is formed toprovide an inclined cam surface 71 which is arranged to engage theroller 69 upon the down stroke of the head 5 for rockingthe shaft'in aco'im ter clockwise direction. The cam 61 is held in its effectiveposition on its down stroke by a stop pin 72 mounted on the bracket 62,and against which the cam is resiliently urged by a spring 73. One endof the spring 73 is connected to the cam' 61, and the other end thereofis connected to a pin 74 mounted on the head 5 ()n the down stroke ofthe head 5. when the cam surface 71 passes the roller normal position(shown in,.l igure 7) under the action of the spring 65, and then, uponthe up stroke of the head 5, the upper face 'of the cam 9 part'i'l-rides on the roller 69 soas to-force the cam 61 outwardly away fromthe stop 72. as shown in dotted outline in Figure 7. On the up stroke ofthe head 5, after the cam is returned to the stop pin 72 the action ofthe spring 73.

In operation, the selected punch 4 is locked to the head5 bythe-insertion of the respective key29. The punches or the key seats arenumbered to facilitate the selection. 7 While the cards are being fed ina step-hy-step movement along the guideway, the head 5 'is continuouslyreciprocated by v the rocker arm 24 so as to move thelower no ends ofthe punches 4 into and out of engagement with the stencil frames 14. Onthe r down, stroke of the head 5, those punches which are not in theselection will merely rest upon the stencil frames 14 without making anyimpression, while .the'selected punches Wlll continue to move downwardly to pierce the stencils under the action of the head 5.. Upon the downstroke of the head 5, the cam 61 moves downwardly into engagement withthe roller 69 and rocks the shaft 60 in a counter clockwise directionsoas to actuate the fingers46. The fingers 46 thereby move into engagementwith two adjacent stencils so as to urge said stencils transverselyagainst the guideblock, lland forwardly against the stop shoulders 42,where they are momentarily held in a precise position o the guideway 2for engage- ,roller 69, the
